公平１−8118号公報に見られるように膨出部形成部分に
膨出部形成用プリプレグを余分に捲着して形成すること
が一般的に行われている。As a means for forming a bulging portion such as a grip portion on a fishing rod, an extra bulging portion forming prepreg is wound around the bulging portion forming portion as seen in Japanese Utility Model Publication No. 1-8118. Is generally done.

である。However, according to such a method, the wall thickness of the bulge formation portion of the fishing rod manufactured is inevitably increased, resulting in an increase in weight, the balance and condition of the rod being disturbed, and the sectional shape of the bulge portion being circular. However, there is a problem in that it is extremely difficult to form a non-circular cross section such as a shape that is easy to grasp or a shape that is easy to mount on a reel. In view of these circumstances, the present invention is lightweight and easy to perform a fishing operation by preventing the strength of the bulging portion forming portion such as the grip portion of a fishing rod from being formed substantially the same as the other portions. The purpose of the present invention is to provide a method for manufacturing a fishing rod.

い。As a means for achieving the above-mentioned object, the present invention forms an enlarged portion having a non-circular cross-sectional shape so that the core bar can be pulled out from the wound prepreg after the thermosetting treatment at the base end part of the core bar. , After winding the fishing rod forming prepreg around the core bar, fitting the heat-shrinkable tube to the fishing rod forming prepreg winding part in the enlarging part of the core bar, and then covering the entire length of the fishing rod forming prepreg winding part. The binding tape is spirally wound so as to partially polymerize, and then, after the thermosetting treatment, the core metal, the binding tape and the heat-shrinkable tube are removed to form a tubular body. The enlarged portion having a non-circular cross-sectional shape formed at the base end portion of the core metal is formed such that the distance from the center to the outer peripheral portion is larger than the radius portion in the maximum circular portion in cross section, and a wound fishing rod forming prepreg is formed. After the heat curing treatment, the core metal can be pulled out to the large diameter side. Further, it is preferable to use silicon rubber, fluororubber or the like as the heat-shrinkable tube, and to increase the winding pitch of the binding tape in accordance with the degree of swelling in the enlarged portion.

る。According to the present invention, after winding a fishing rod forming prepreg around a cored bar having an enlarging portion having a non-circular cross section that can be drawn out after thermosetting treatment, a heat-shrinkable tube is provided only on the outer peripheral portion of the enlarging portion of the fishing rod forming prepreg. After applying, the binding tape is wound around the entire circumference in a spiral shape and heat-treated to heat-shrink the flow of the synthetic resin impregnated with the prepreg for fishing rod formation in the enormous part during heat-hardening. In order to prevent the strength from decreasing by forming a uniform thickness in the enlarged part by suppressing it with a flexible tube, let the synthetic resin impregnated in the fishing rod forming prepreg flow out from the gap of the binding tape in the circular section of the core metal. While being heat-cured, the cored bar is pulled out to produce a tubular body, and a lightweight, thin, and well-balanced fishing rod having a bulging portion such as a grip portion is manufactured.

A non-circular enlarged portion 2 is formed at the base end of the bulging portion 2, and the bulging portion 2 has a sectional shape in which a distance b from the center to the outer peripheral surface is larger than a radius a of the maximum circular portion of the core metal 1 in section. It is formed so that it can be pulled out to the large diameter portion of the cored bar 1 after the thermosetting treatment described later. After winding the fishing rod forming prepreg 3 around the core metal 1 having the enlarged portion 2 formed at the base end in this manner, the heat shrinkable tube 4 is fitted to the outer peripheral portion of the fishing rod forming prepreg 3 in the enlarged portion 2. Then, the prepreg 3 for forming a fishing rod and the heat-shrinkable tube 4 are temporarily contracted, and then a thin tape 5 such as cellophane is wound around the outer circumference of the prepreg 3 so as to partially overlap with each other. It is preferable that the winding is performed such that the winding increases according to the degree of bulging. After heat-curing the core metal 1 in this manner according to a conventional method, the core metal 1 is pulled out to the enlarged portion 2 side, and the binding tape 5 and the heat-shrinkable tube 4 are peeled off to manufacture a fishing rod of the tubular body 6. The surface of the bulging portion 6'of the manufactured tubular body 6 is formed smooth and does not require polishing, and the portion 6 "on which the heat-shrinkable tube 4 is not adhered has the binding trace of the binding tape 5 wound thereon. The fishing rod forming prepreg 3 is made of the same reinforcing fiber sheet as the conventional one impregnated with thermosetting synthetic resin, and is further reinforced at the boundary with the enlarged portion 2 if necessary. It is also possible to polymerize the prepreg 3. When winding the binding tape 5, the fishing rod forming prepreg 3 is wound and then wound over the entire length thereof to bind the fishing rod forming prepreg 3 first. Heat after peeling off the binding tape 5 for only the two large parts When the shrinkable tube 4 is fitted and temporarily contracted, and then the binding tape 5 is again wound around the heat-shrinkable tube 4, the fishing rod forming prepreg 3 in the enlarged portion forming portion is efficiently bound and a high-quality fishing rod is provided. Further, as shown in Fig. 10, if the pattern forming template 7 is placed in advance before the heat shrinkable tube 4 is fitted and removed after the tubular body is manufactured, the tubular body 6 is produced as shown in Fig. 14. Bulge 6 '
The concave pattern 7'can be integrally formed by the pattern forming template 7.

を作業能率良く容易に製造することができる。In the method of the present invention, a fishing rod forming prepreg is wound around a cored bar having a bulged portion having a non-circular cross-section that can be drawn out after thermosetting, and only the bulged portion for fishing rod formation of the bulged portion is wound. Impregnation of a fishing rod forming prepreg in a bulging part where strength is apt to decrease by applying a heat-shrinkable tube and then spirally winding it together with other parts in a binding tape. It is possible to form the bulging portion with a substantially uniform thickness while suppressing the deformation, and the tapered circular tubular portion with a relatively small change in strength can be formed with a uniform thickness as thin as possible, and the strength balance can be obtained. It is possible to efficiently manufacture a fishing rod having a bulging portion such as a lightweight grip portion. Further, since the bulging portion of the fishing rod according to the method of the present invention is formed smooth and does not require polishing, it is not necessary to polish the bulging portion that is difficult to polish, and the strength is not lowered by polishing, and the weight and the strength are low. A fishing rod having a stable bulging portion such as a grip can be easily manufactured with good work efficiency.
